Application filed October 9, 1908. Serial No. 456,997.

To all whom 'it may concern:

Be it known that I, BENJAMIN F. CAR- PENTER, a citizen of the UnitedStates, of 625 Chestnut street, Roselle Park, county of Union, and Stateof New Jersey, have invented certain new and useful Improvements inCooking-Cabinets and Heat-Conservator-s, fully described and representedin the following specification and the accompanying drawings, forming apart of the same.

This invention relates to an attachment for cooking stoves and ranges,and consists of a casing set upon the stove, with segmental guardshinged thereon and adapted to turn downward when in use to whollyinclose the top of the range. These parts form a cooking cabinet, whichI also term a heat conservator, as it greatly economizes the use offuel.

The invention performs the following functions: First, it shields thecook from the emanations difiused by the operation of cooking, amongwhich are radiated heat, spattering fluids such as gravies, pot liquor,batter, &c., sudden bursts of flame, gases, hot coals, ashes or otherinjurious, disagreeable or offensive emanations. Second, it secureseconomy of fuel by utilizing the heat for the purpose of cooking orother household operations, such as laundry work, &c. Third, itmaintains sanitary conditions in the kitchen and adjacent roomsbypreventing excessive heat in hot weather, and the diifusion of smoke,greasy particles, dust, steam and vapors which soil and tarnish, andoffensive odors which, when not confined, pervade to some extent theentire house in which the cooking is done. Fourth, it furnishes acapacious warming chamber including the whole area upon the top of thestove; in which one or more compartments can be provided, and the heatin such compartments variously regulated so that all food in pots ordishes can be preserved in a regulated atmosphere at any degree of heatdesired. Fifth, it furnishes abundant shelf space for food, dishes andmiscellaneous cooking and stove appliances. Sixth, it carries off thegases arising from banked fires, so as to secure (without injury to thehealth by the diffusion of poisonous gases) the greatest economy infuelcombustion during the night or other periods in which active firesare not required.

Seventh, it enables the housekeeper to c011- trol and regulate the heataccording to the temperatures of various seasons, thus reducing the heatof the kitchen fully twenty degrees in summer,and thus rendering itcomfortable; and confining the heat to the stove or range in winter, soas to utilize it most economically in heating and cooking operations.

The invention thus furnishes the means [whereby scientific sanitaryoperations of cooking can be effected in a comfortable and healthfulatmosphere, and cooks educated in domestic economy, especially in theeconomical use of fuel, and in the control of heat in such a manner asto produce the best results.

The invention will be understood by reference to the annexed drawing, inwhich- Figure 1 is a front elevation of the top of a stove with thecabinet thereon and the front of the casing closed; Fig. 2 is an endview of the same parts with the nearer end of the casing removed; Fig. 3is an inside elevation of one of the corner posts of the casing; Fig. 4is a plan of such post with the front end of the pivot-frame; Fig. 5 isan elevation showing the detachable joint between.

the back and the top of the casing; Fig. 6 is a plan showing thedetachable joint between the back and the ends of the casing; Fig. 7 isan elevation showing the detachable joint between the top and the endsof the casing; Fig. 8 is a vertical section of the cabinet on line 88 inFig. 1 with the segmental doors turned up inside the top of the casing;Fig. 9 is a front elevation of the same parts with the casing in sectionon line 99 in Fig. 8; Fig. 10 is a plan of one end of the casing and itsreinforcing cast metal frame, with the pivot shown in section thereonand the means for operating the brakes; Fig. 11 is a cross section atone edge of one of the door seg: ments, taken on line 11-11 in Fig. 9Fig. 12 is a section of one of the segmental doors on line 1212 in Fig.9; drawn upon a larger scale than Fig. 9, with the friction disk removedand the door turned upwardly as when inside the casing; Fig. 13 showsthe inner end of the arm upon such door turned and the spring contractedthereby; Fig. 14 is a front View and Fig. 15 a plan of the frictiondisk; and Fig. 16 is an edge view of the arm-hub with art of the armthereon.

To facilitate the transportation of the cabinet, the casing is made withdetachable folded vseams, the back A having hook flanges at the ends toengage folds a upon the rear corners of the end-pieces B. The back A ofthe casing is provided at the top with a downwardly bent flange A havinga lip A bent upward at its lower end to receive a hook C at the rearedge of the top.- piece C, as shown in Figs. 5 and 8. The ends and frontof the top-piece C are furnished with similar hooks C, as shown in Figs.7 and 8, and the endpieces B, as shown in Figs. 7 and 9, are also formedwith reflexed flanges A and lip A to engage the hooks C, but the top ofthe flange A projects above the top C at the back and ends, to preventarticles placed thereon from slipping off.

Inside each of the ends 13, a cast-metal frame is secured by rivets B,being formed with a horizontal bar I) and an upright leg E, and a pivotat the junction of the bar and leg formed, as shown in Fig. 10, withhollow graded ournals a, Z), 0, upon which the arms of thesegnientaldoors are jointed.

The front corners of the casing are pro-. vided with posts F riveted tothe bar D at (Z and having a front flange F with progressivelyprojecting steps or shoulders G thereon to limit the downward movementof the a, -11 and 0.

doors. The leg E and post F are provided with feet 11 to rest upon thetop of the stove to be secured thereon by a bolt I, as shown in Figs. 1,2 and 9.

To wholly expose the top J of the stove J (partly shown in Figs. 1 and2) the casing is preferably made so that the inner edges of the postsset over the ends of the top, as shown in Fig. 1; the feet H projectinginwardly to rest upon the stove top, as shown in that figure.

' The sheet-metal ends B of the casing are extended under the feet tocontact with the stove top, as shown in Fig. 9, and form a bottom jointbetween the stove-top and the cas 111g.

The door-segments K, K, K are shown three in number, of progressivelyincreasing length and provided each upon its forward corner with ahandle M to, move the segment, and formed with arms K which are securedto the hubs L, shown in Figs. 12 and 16, and such hubs jointed upon thejournals These journals are graded or progressively reduced in size toform a succession of shoulders d, as shown in Fig. 10, against which thehubs may be pressed to produce a frictional resistance to the movementof the doors. The hubs of the several arms have holes 6 which are gradedor pro.- gressively reduced to fit and turn loosely upon the gradedjournals. The hub of each arm covers only a portion of the space uponits ournal and is set in contact with the shoulder (Z to form a brakewhen pressed against such shoulder.

The journals are Inadehollow and each formed with a slot f in which theinnerend g of a spiral wire spring 9 is locked, the outer end g of thespring being bent outwardly to engage one of several lugs Z upon the hubL; these furnishing a means of varying the effect of the spring upon thedoor segment to which the hub is attached,

The journal is stationary and the spring is so adjusted that when eachdoor is in its upright position, as shown in Figs. 8 and 12, the tensionon the spring is diminished, and as the doors are turned downwardly toclose the casing and cover the front of the stove top the tension of thespring is increased and operates to counterbalance the weight of thedoor, which is effective in such position. In addition to suchcounterbalancing, a frictional resistance is opposed to the movement ofthe'door to prevent its accidental displacement when set in any desiredposition. Such resistance is produced by a friction disk It fitted uponthe ournal v and the cross-pin i fits in such notches andextends acrossthe journal, where it is en? gaged by a hook on upon the inner end ofthe bolt j.

The hollow chamber 11, within the journals is extended to the outer sideof the frame DE, and a bearing-block 0 is fitted to the outer end ofsuch chamber to support the nuts 29 upon the ends of the three bolts jwhich are required to operate three disks for the three door-arms.

The tightening of one of the nuts 79 presses the disk with which it isconnected toward the spring, which in turn presses the hub L of thedoor-arm toward the shoulder d upon its journal, thus producing africtional resistance which may he graduated in any degree to hold thedoor when placed in any adjusted position by hand.

The relation of the progressively projecting shoulders G to the arms ofthedoor front of the casing, while permitting any of the segmental doorsto be raised independently of the others, sufliciently to expose thespace behind such doors.

The lower door-segment K maybe turned downward in contact with the stovetop without turning downward the two upper door-segments, thus exposingthe interior of the casing for the operations of the cook, whileprotecting the cook from the spattering of anything set upon the stovetop.

lVhen desired, the two upper door-segments may be turned into theiroperative position shown in Fig. 2, and the lower segment K turnedupward inside the same, to permit the placing of any utensil upon thestove top or removal of one therefrom, or stirring its contents withoutexposing the cook to the entire radiation ofheat, and at the same timeconfining the gases and vapors to the interior of the doors and casing,as they rise inside the upper segments. The stovepipe N is shown in.Fig. 2 extended upward from the top J of the stove, through the rear artof the casing and through the top C. The back A thus lies behind thestove-pipe to inclose the same.

The pipe connected with the stove top is commonly made of oval form, andis therefore shown of greater width than thickness in Figs. 1 and 2,with a round pipe N extended therefrom above the top 0 of the casing. p1

Below the top of the casing, a damper g is shown inserted in the wallofthe stovepipe or in a casting fitted thereto, and a pullrod 7' extendedtherefrom to the front of the casing by which the damper may be openedat any time to produce an upward draft within the casing, which drawsall the vapors and gases into the stovepipe N.

The door-segments are made of graded radii so as to nest one within theother, the succession of journals ((6, b and 0), upon the pivots for thearms K permitting the arms to play within one another the same as thesegments, as clearly shown in Fig. 9.

The stops G upon the flanges'F of the corner posts permit the forwardmovement of the several doors in different degrees so that they standone above the other when lowered to wholly inclose the front of thestove-top and casing, but they do not prevent the lifting of any of thedoor-segments independently. The stops project outward progressivelyfrom the top to the bottom of the posts, and bring the successiveportions of the posts adjacent to the arms K of the several doors, andthus partially close the spacebetween the ends of the doors and the endsB of the casing. 1 To close the space between the several segments K, K,K the outer segments are formed at their front and rear edges, as shownin Fig. 8, with inwardly projecting flanges s which clear the outsidesof the inner door-segments, but substantially close the opening betweenthe segments in both the open and closed positions of the segments.

The door-segments are preferably made with double walls, as shown inFig. 12, to

form an airspace 2, which prevents the radiation of heat when the casingis closed.

The flanges 8 shown in Fi 8 arein such case formed as shown in Fig. 12,and the front and rear edges of the segments at the same timestrengthened, by folding .the sheet metal of thesegment K or K around astrip of hoop iron u and locking the edges of the inner wall 1) within aflange o bent around the inner side of such strip.

To 0001 the air-space in the door-segments and further prevent theradiation of heat, holes w are formed through the edgesof the segmentandv holes w through the walls of the air-space; these holes permittingcold air to pass through and into the segment and thence to the chimneywith the vapors in the cabinet.

Ventilation for the wire springs g is also provided through the hollowinterior of the hollow journals a, b, 0, which are formed upon the upperand lower sides with slots 7 (shown in Figs. 10 and 12) to permit thecross-pins t to move longitudinally of the journal as the bolts j aretightened. In Fig. 10, the end B of the casing i shown at the right andleft hand sides of the hollow chamber 1?, which extends from thejournals to the outer side of the frame and thence outwardly through theend plate B. The cold air entering the hollow journals from outside thecasing passes through the slots a into direct contact with the coils ofthe wire springs g and thus prevents the heat from impairing the temperof the springs.

A shelf 00 is shown in Figs. 1 and 2 supported by legs w upon the bars Dwithin the ends of the casing, the shelf being made shorter than theshortest door-segment so that the segment arms may pass its ends whenturned upwardly, as shown in Figs. 2

and 8. The shelf is shown perforated for the passage ofthe stovepipe N.

In Fig. 8 a hole 6 is shown in the top 0 over the shelf 00, with thebulb (Z2 of a thermometer inserted through the hole to indicate thetemperature of the casing. A cover 6 is shown pivoted upon the top by arivet c to close the hole when the thermometer is not in use. By the useof the thermometer and the adjusting of the damper, the temperaturewithin the casing may be regulated as desired. It is to be understoodthat any of the segments can be placed in an operative positionindependently of the others, because they are fitted, as shown in Figs.8 and 9, to

foot on the upright leg E, the two feet at each end of the casing thusholding it securely in place upon the stove top.
